Not only have his fellow Londoners forgotten most of what humankind used to know, before civilization collapsed, but they don't particularly care to re-learn any of it. Though he is at first disconcerted by the failure of his own era's smug doctrine of Progress, Tuft eventually decides that post-civilized life is simpler, more peaceful. That is, until northern English and Welsh tribes threaten London -- at which point he sets about reinventing weapons of mass destruction.Shanks's post-apocalyptic novel, a pessimistic satire on Wellsian techno-utopian novels, was first published in 1920.
